Together with the Campbell Collaboration and the University of Mannheim (SFB 884), C4ED organized a workshop on systematic reviews and meta analyses in international development. With more about 50 participants from across Europe and beyond, the two-day event equipped researchers with core principles of systematic reviews and the statistical tools to conduct meta-analyses. Dr. Ashrita Saran from the Campbell Foundation’s South Asia office and Dr. Bernd Weiss from the GESIS institute in Mannheim delivered an interactive format of lectures followed by hands-on sessions where participants performed meta-analytical analyses using R or stata. C4ED is grateful for both the speakers’ and the participants’ dedication towards an evidence-based policy movement, and is looking forward to welcoming interested researchers in the future again.
